Low-dimensional (LD) organic-inorganic hybrids have recently emerged as exciting electrocatalytic nanomaterials in which the 0D-1D, 1D-2D, or 2D-2D electrochemical interfaces can be finely tuned to generate unprecedented features that are not perceived in their individual counterparts. LD interfaces have shown incredible advantages in regulating electron transfer, charge polarization, bonding energy, and the adsorption energy of intermediates of crucial electrocatalytic reactions. In this perspective, we provide our own understanding of the chemical aspects that govern the interfacial effects at LD hybrids based on our experimental and theoretical points of view. The discussion also covers the in-depth relationship between the dynamic interfaces and the electrocatalytic activity of LD heterostructures, as well as the more recent achievements to disentangle the catalytic mechanisms using advanced in situ spectroscopy techniques.

低维 (LD) 有机-无机杂化材料最近已成为令人兴奋的电催化纳米材料，其中 0D-1D、1D-2D 或 2D-2D 电化学界面可以进行微调，以产生前所未有的特征，而这些特征在其各自的对应物中是无法察觉的。 LD 界面在调节关键电催化反应的电子转移、电荷极化、键合能和中间体的吸附能方面显示出令人难以置信的优势。从这个角度来看，我们根据我们的实验和理论观点提供了我们自己对控制 LD 杂化物界面效应的化学方面的理解。讨论还涵盖了动态界面与LD异质结构电催化活性之间的深入关系，以及利用先进的原位光谱技术阐明催化机制的最新成果。
